This is my first MOC in 2010. It was created after I had failed on my two previous creation (not published). I had a hard time with this one - I almost disassembled it! But here it is:
Length 520 mm
Length with fork: 640 mm
Axle span: 224
Weight: 3088 g
Max speed: 0,11 m/s
Min angle: ~ -11 degrees
Max angle: ~ 63 degrees
Length: 480 mm
Length with extended boom: 720 mm
*Length without fork.
Extending time: 30 s
Max operating height: 440 mm
Boom raising: 85 s xD
Boom weight: 715 g
Fork span: 64 mm
Length: 90 mm
Width: 162 mm
Height: 112 mm
With huge breaks - 7 weeks. But if you count only days I was modifying/adding bricks it would be around 2 weeks.
In MOC I used:
The parts I used. Each motor's application I will describe later.
2 x XL
8 x M
1 x old motor
2 x switch
1 x New BB
9 x extension cable (5 x 200mm, 4 x 500 mm)
4 x IR
7 x Lights
2 x Large pneumatic cyllinder (dummy)
1 x small pneumatic cyllinder (dummy)
5 x Clutchgear
2 x LA
7,5 m of cables, 11 motors in total.
Detailed description is found below this list.
1) 4x4 drivetrain, full independent suspension, 2 shock absorbers per each wheel
2) steering - two modes: normal and crab, steering mode switching
3) Jib raising
4) Jib extendind
5) Fork angle regulation
6) Cabin light (switching ON/OFF)
7) switching on/off of nightime lights (manually controlled)
8) V6 engine dummy
9) raising engine hatch and opening cabin doors (manually controlled)
Drivetrain & Steering:
In vehicle there are two PF XL motors used for propolsion, 2 mediums for steering and another medium for changing steering mode. To stop sliding off the axles from gears in differentials I used hose ribbed (as can be seen in the pic above). The turning radius is very low and vehicle is extremely manouverable (for it's scale of course) due to very short axle span.
To raise the boom I use 2 medium motors. It may seem that I added the second motor just to increase the motors' number. Please remember the boom weigths over 715 g WITHOUT any cargo. It is 720 mm long when fully extended and can be operated between -11 and +63 degree angle. When you use two LAs and two motors you need to sum the moments and then pass it along to the common shaft. To raise the boom it takes... 85 s :)
Second part of the boom elongates it for 260 mm. It takes 30 s to extend it and then the maximum operating height is 440 mm.
I think this is the first fork angle andjustment in Technic forklift. The medium motor is used to adjust the angle and it is at the end of the second section of the boom. The angles allow to hold steadily the pallet on the fork.
In front there are two outriggers. Although they can't completey raise the front of the vehicle but they allow to raise it a bit - a lot of weight is still supported by the suspension and wheels. They are operated by old motor. I used it to shorten the vehicle for 2 studs.
V6 engine dummy:
On the right side of the vehicle there is an engine dummy propelled all the time by medium motor.
Is equipped with backlight (remotely controlled), as well as the air conditioning and specialised computers used for controlling of the vehicle. You can open the doors. I had to fit two IRs in the back of the cabin - i know it doesn't look good but it was the only place available.
You can open the engine dummy hatch and see the pistons moving from above and from the right side through the ventilation grate.
At the back of the vehicle there is a switch used to control the lights - 2 pairs of white in fron, 2 pairs in front on the boom and 2 pairs of red in the back.
Two other IRs I managed to hide before the fron axle and behind the outriggers.
I managed to locate it at the rear side of the vehicle. It's accessible. With so huge number of motors and electric parts battery's capacity lasts for 15 minutes of fun and then it needs to be recharged:)

I hope you like it. Enjoy!
